BossBar is not showing...

i tried

PHP:

$ak = new AddEntityPacket();
$ak->type = Entity::ZOMBIE;
$ak->entityRuntimeId = Entity::$entityCount++;
$ak->position = new Vector3();
$ak->metadata[Entity::DATA_NAMETAG] = [Entity::DATA_TYPE_STRING, "Title for the bossbar"];
$sender->dataPacket($ak);

$pk = new BossEventPacket();
/** @var Zombie $en */
$en = Entity::ZOMBIE;
$pk->bossEid = $en->getId();
$pk->title = "Title";//this will probably get overridden by $boss->getNameTag()
$pk->playerEid = $sender->getId();
$pk->eventType = BossEventPacket::TYPE_SHOW;
$pk->healthPercent = 50;
$pk->unknownShort = 1;
$pk->color = 1;
$pk->overlay = 1;
$sender->dataPacket($pk);


and it sends no bossbar. but if the $pk->bossEid is $pk->bossEid = $player->getId() it gives me bossbar but it sends the players nametag i dont want that unless i can change the title

 

Hmm...

 

I tried $ak->bossEid = Entity::ZOMBIE it dont work

 

bossEid is supposed to be the runtime ID of a spawned entity, not the entity type

 

how do i get that
